Zballabhbm it mayconcerm Be it known thatI, ROBERT Bunow, residing at Knippelsbrogade. 2, Copenhagen,

Denmark,- having invented certain new and.

useful Improvements in Interchangeable Bodieswfor Automobile-Chassis, do hereby declare the following to be a full and clear description of thesame. i

V My-invention relates tothat type of device which permits of the substitution of a limousine body for a delivery, touring, roadster, or othertype; of body.

My. invention aims to provide-a'fastening device especially adapted for retaining any of these bodies to the frame work of the automobile,-so that it is practically impossible for any of them to become displaced, although one may be substituted for the otherin' a. very short period. 1

My invention is disclosed in the accompanying drawings, in which Figure l is aside elevation of an autom bile. 1

Fig. 2 is a rear elevation showing the body in section.

Fig. 3' my improved form of joint, which preventsthe displacement of the body-when once in applied position.

Fig; at discloses a runner, which in addi-.

tion to preventing wear to the body upon being moved from and to the frame work also makes this operation moreeasily performed. i

Figs. 5, 6, 7 and 8' disclose the device which I use to secure the body. a i

, r si 9, 10, 11,12, 13,14, 15 and 16,

various views of; my joints, which fuse to prevent displacement, or'movement of the forward, 2'. e. permanent part of the body with'respectto the rear, 2'. e. removable part of thebody.

Referringmore particularly to the figures,

1 discloses part of .the frame of the chassis; 2,a,. supporting bar which is provided withopenings 2 adapted toreceive a bolt '2 provided with a nut 2; 3, thepermanent part of the body, 2'. e. the forward part which: has a rearwardly extending portion 41 which forms part of my improved joint, hereinafter more particularly descrlbed, and

5: designatesthe body of a van. provided with.

a lug 6,fon1ned with an opening. It will: be noted that Ihave provided these Specification of Letters Patent. 1 Patg t fl N 2*? 191"? Applicationfiled January 25, 1916 Serial No. 74,212.

facilitate theirmovement on to and off of the frame 12, Fig. 3.

In Figs?) and 4 I have, as aforestated, cut the end of sill 4*, diagonally and the end of runner 7 in a manner to correspond to the end of the sill. It will be further noted that the lowermost portion of the runner 7 is adaptedto project under the uppermost portion of sill 1. The end of the sill l is cutdiagonally and. is formed with two faces,

oneof said faces being positioned to the 7 brought into proper position.

In Figs. 14c, 15 and 161 disclose my preferred form of joint. Similar to that shown in Figs. 3 and 1.0 I provide a diagonal cut to the sill: 4: and the runner 7, these cuts to correspond one to the other. On the under side of the runner7, I provide a socket 11 into which is adapted to project, when the sill 4E andrunner 7 are in applied position,

the tongue 10, secured to the sills by means of a faceplate 9. I have provided, as disclosed in Fig. 16, the runner 7 with a diagonal side cut, which correspondsto cut in sill, to furtherprevent side movementof the runner 7 with respect to the sill a.

As disclosed in Figs. 12 and 13, 1. have provided a. prong, adapted to be mounted, asdisclosed in Fig. 1d, at a position above the runner'7, to further insure theprevention of shifting movement of the removable body with respect to the fixed one. Secured to, thelsupporting bar 2 is a bolt 17,. of a form particularly adapted for the work for which I intend usingsame. This bolt is mounted on plates, which are secured to the supporting bar 2 by means of a bolt 15,

which further retains a mud guard carrier 16 in appliedposition. Extending through the plates is the shank of the bolt 17 which is provided with a conical body portion 18 terminating in a threaded shank, upon which.

is mounted, a nut 19.

bracket 20 provided with a down struckpor tion 21 in which is formed a conical opening corresponding to the body portion 18 and the bolt 17.

It will now be obvious that when I desire to secure a body to the chassis 1 that this may be accomplished by sliding the body I v I desire to claim 1s by means of a runner 7, on to the frame work 1 and the cross bar 2 as faras possible. The screw threaded end of the bolt 17 will then project through the opening 22 of the bracket 20. When it is now desired to fixedly secure the removable body to the permanent frame the nut 19 will be mounted upon the screw threaded end of the bolt 17 and rotated, whereby the bracket 20 and bolt 17 will be drawn closer one-to the other and as the bolt is fixedly mounted on the permanent part of the automobile and the bracket 20 mounted in the same fashion upon the removable body, these latterportions will be drawn one to the other, whereby the tongues 10 will be caused to enter the sockets 11, the diagonal cut of the runner 7 to be engaged by the corresponding out 4 of the sill, the prong 13 mounted upon the body 5 to enter a corresponding recess in the rear of the seat '3 whereby the removable body will be retained in applied position.

A second Way of securing the body to the chassis 1 is by sliding the body in the usual manner, by means of the runner '7 on to the frame work 1 and the cross bar 2 as far as possible. The lug 6 will then abut against the cross bar 2 at 2 and a bolt2 will then be inserted through the opening, so that the screw threaded portion projects beyond 2 and through the opening in the lug 6. A nut will then be secured to the screw threaded portion and upon the rotation of such nut the body will be drawn forwardly toward the statlonary seat, the diagonal cut of the runner 7 being engaged by the corresponding cut 4; of the sills, thus forcing the former firmly upon the chassis, making it possible to-rely solely upon the nut and bolt to retain the body proper in applied position. In connection with this it is pointed out that it is not necessary for applicant to limit himself to a diagonal cut for this purpose.

Any suitable means which would enga e the end of the runner 4: and upon being into position would tend to bring the end of runner 7 in to proper position, Would be perfectly suitable for thi purpose and applicant accordingly does not wish to limit himself to the specific means illustrated.

It hould be borne in mind that numerous devices have been patented which allow of the removing of one form of automobile body and the substitution of anotheiybut it is contended thatnone of these accomplish thisend with the simplicity which marks ap- .plicantsdevice. It will be noted that all that is necessary to engage ordisengage the removable portion from the permanent is to rotate the nut 19 upon the screw threaded ends ofthe bolts '17 and thereafter simply the y rearwardly' and away from the chassis.

Having thus described myinvention, what 11A vehicle comprising a chassis, a sill drawingthe runner and sill together, such means comprising a ,bolt mounted on thechass'is, such bolt being providedwith' a conical shank and terminating in a screw-r threaded end portion, a bracket secured to the body, such bracket; being formed with an opening through which the end of the bolt is adapted to project,'a nut for engaging the crew-threaded end'portion' offsaid bolt whereby, upon said nut being rotated,

the runner and sill willbe drawn together-.
